The A♯ minor 7th flat 9th minor 7th flat 9th chord extends the minor 7th with a flat ninth B, creating a dark, eerie tension. The combination of the minor third C♯, minor seventh G♯, and flat ninth B produces a dissonant, haunting sound perfect for jazz, film scoring, and dramatic resolutions. With G♯ in the bass, this voicing functions as the 3rd inversion of A♯ minor 7th flat 9th.
Also written as A♯min7(♭9), A♯m7♭9/G♯, and A♯m7(♭9)/G♯.
